PUMP AND PUMPING-ENGINE.

$IPEGIFICATION forming part of Letters Patent No. 457,022, dated August4, 1891.

Application filed December 6, 1890. Serial No. 373,800-

To on whom it may concern:

Be it known that we, WILLIAM HENRY BAI- LEY and GUSTAVE LINDEMANN, bothsubjects of the Queen of Great Britain, and residents of Salford, in thecounty of Lancaster, England, have invented certain new and usefulImprovements in Pumps and Pumping-Em gines, (for which we have obtainedLetters Patent in Great Britain, No. 1,192, bearing date January 23,1890,) of which the following is a specification.

Our invention relates particularly to improvements in thosepumping-engines-such as sinking-pumpsin which a rain or rams, incombination with a steam-cylinder, is employed; but our improvements canbe applied to pumps actuated by a separate motor.

In applying our improvements to a pump for well-sinking we employ asuitable steamcylinder, the piston rod of which passes through thebottom of the cylinder andis connected to a pair of cylinders orpump-barrels, in each of which is fitted a hollow piston or guide, thefirst hollow piston forming part of the discharge-pipe for the water.ond hollow piston is in connection with or forms an air-vessel. To thepair of cylinders or pump-barrels is connected the hollow ram of thepump-cylinder, which latter is 'fitted with a suitable number oflifting-valves near the bottom, the other lifting-valves being fitted atthe base of the two cylinders near the top of the hollow ram. A sniftingvalve or valves is placed above or below the valves at the bottom of thepumpcylinder, and in order to connect the different parts of the pump together suitable tie-rods are secured between the steam-cylinder andpump-cylinder, the

Whole machine being suspended by chains when employed in sinking wells.The abovementioned air-vessel obtains a supply of air from the sniftingvalve or valves and serves to prevent shocks when the pump-valvesoperate.

In our improved pump the steam-cylinder, the hollow pistons, and themain pump-barrel remain stationary, the two cylinders or pump-barrelswith the main ram being moved by the piston-rod of the steam-cylinder,the moving parts being guided by the two stationary hollow pistons.

In order that our invention may be fully understood and readily carriedinto effect, we will describe the accompanying sheet of draw ings,reference being had to the letters marked thereon.

nected to the dischargepipe c and the piston (1 forms an air-vessel. Thepump-barrels c and d slide on the pistons or guides c and d, whichtogether constitute well-balanced guides and enable the pump to worksmoothly and without side strain.

f is the pump-cylinder, in which the ram 6' slides.

h is the shifting-valve, and g g are the lifting-valves at the bottom ofthe cylinder f.

t is the inlet-pipe.

jj are tie-rods, which connect the pump-cylinder f to the steam-cylindera, and k k are chains by which the pump is suspended.

The mode of operation is as follows: hen steam is admitted to thecylinder a, the piston 21 moves downward and carries with it thepump-barrels c and d and the hollow ram e, the valves 6 e lifting. Whenthe piston b, barrels a and (l, and ram 6' rise, the valves 6 e areclosed and some of the water above the valves c c is discharged throughthe pipe 0 The snifti ng-valve 7L admits air into the pumpbarrel f,.asusual, and a portion of the said air finds its way to the air-chamber inthe hollow piston (Z. In case of a separate motor being employed tooperate the pump, it would be necessary to apply the power to move thetwo pump-barrels and the main ram.

Having now particularly described and as certained the nature of oursaid invention and in what manner the same is to be performed, wedeclare that what we claim, and desire to secure by Letters Patent ofthe United States, is--- In a lift-pump, the combination, with the InWitness whereof we havehereunto set our 10 discharge-pipe 0 on which thepump-barrel hands in presence of two witnesses. slides, and the hollowpiston or guide c,f0nning part of said discharge-pipe, of the hollow W.H.
